内容記述 | The outcomes of previous high-velocity impact experiments using Yakuno basalt targets have been used to validate numerical codes of fragmentation developed in the context of planetary science. However, the distribution of incipient flaws in the targets, usually characterized by the Weibull parameters, has generally be implemented in the codes with values allowing to match the experimental outcomes. Here we follow the original method proposed by Weibull (1939) to measure these parameters for this Yakuno basalt. We obtain a value of the Weibull modulus m larger than the one obtained from simulation fits to the experimental data. The second Weibull parameter, called k, related to some characteristic strength of the material is also larger than those typically used in the simulations. However, the combination of the two parameters represented by ln(kV/m), where V is the volume of the target, has a value which is similar to the one allowing simulations to match the experiments. Future numerical simulations shall then use this new set of parameters to check that they still reproduce the experimental outcomes. | |||||
